Schema Markup Validator & Recommendations

Schema Markup Validator & Recommendations

Validate existing structured data and see what should be added for the selected website and page type.

What should be checked?
For online shops and catalogs with products, prices, availability, and online ordering.

Follow the questions in order. The first question where you answer "Yes" determines your website type (do not proceed further).

1. Do you sell products through an online catalog with prices and a shopping cart?
Yes → «Online store» · No → step 2
2. Is your physical location in a specific city/district important to the client (they choose you partly due to proximity)?
Yes → «Local business» (address and opening hours are key) · No → step 3
3. Does the site feature individual service pages with transparent pricing that clients can order immediately?
Yes → «Service business» (mobile/on-site, online, remote) · No → step 4
4. Do you sell access to software/app through subscriptions or pricing tiers?
Yes → «SaaS & Software Product» · No → step 5
5. Is the primary content articles, news, or videos (rather than products/services/software)?
Yes → «Media & Content» · No → «Corporate website» (complex B2B contracts, sales team lead forms, custom software development/consulting without fixed online pricing)
Carefully select the website and page type — the accuracy of the audit and markup recommendations directly depends on them.
URL mode analyzes raw server-rendered HTML (SSR). Injecting structured data via client-side JavaScript is not recommended: Yandex and AI bots do not execute scripts and will miss it entirely, while Google processes JS with significant delays. Serving Schema.org directly in initial HTML is the SEO best practice.

The ITSEO Schema Markup Validator delivers comprehensive diagnostics and actionable recommendations for structured data in JSON-LD, Microdata, and RDFa formats. Beyond basic Schema.org syntax verification, the tool evaluates your markup against the specific business profile and page type — including ecommerce, service providers, local businesses, corporate portals, SaaS platforms, and content media. This provides clear visibility into which entities are properly implemented, which required properties are missing for Google rich results and Yandex snippets, and which atypical structures should be reviewed.

The audit is performed directly on raw server-rendered HTML (SSR), reflecting the industry gold standard in technical SEO: markup served directly from the server is immediately accessible to all search engines, AI search crawlers (Google AI Overviews, Perplexity, Copilot), and social graph parsers without relying on delayed client-side JavaScript execution. The validator intelligently distinguishes top-level entities from nested helper objects (such as shipping details, geographic coordinates, or sitelinks search actions), preventing false positive warnings.

Each recommendation includes precise property requirements, field descriptions, and best-practice examples. When missing or incomplete markup is detected, you can seamlessly transition to the ITSEO Schema Markup Generator with prefilled page data to create valid, error-free JSON-LD in seconds and boost your search appearance.
